Programming in Modern C with a Sneak Peek into C23
summary
C shows concrete, modern tricks: compound literals enable in-place default-argument–style structs and zeroing (example prints 42 and even Unicode); designated initializers let sparse or out-of-order field setup (an initializer list produces an array size of 12 in the demo); flexible array members replace two mallocs with one contiguous allocation. Examples use GCC trunk and Compiler Explorer (C23 landed last week, _Bool became a keyword); generic selection macros and VLA/static array parameter checks (malloc size for a 10x10 int array = 400 bytes) are demonstrated.
